TRAP.

Application tiled September 'flhis invention relates to traps, and hasfor its object the production of a simple and eltlcient trap especiallyadapted for use in connection with waste-pipes for preventing the escapeoi sewer gases.

Another vobject of this invention is the production of a simple andellicient 'trap having a deep water-seal, and having the inlet andoutlet openings formed near the bottom of the trap in such a manner asto prevent sewer gas escaping into a room even should the cover beentirely removed from the trap while cleaning.

A further object or" this invention is the production of a simple andellicient means for 'facilitating the cleaning of the trap7 should thesame become clogged by providino a pair ol' aligned clean-out openingsor ports formed within the casing ot the trap, and arranged so as topermit the cleaning tools or wire to be inserted without the necessityof removing the top of the trap or disconnecting the trap from the pipeline.

lWith these and other objects in view, this invention consists ofcertain novel construction, combinations and arrangement of parts whichwill be hereinafter fully described and claimedln the drawing:

The ligure is a vertical sectional View through the trap.

By referring to the drawing, it will be seen that 10 designates the bodyof the trap which comprises a substantially vertically arranged tubularbody having a vertically extending tubular member 11 Jformed integralwith the body 10 and separated from communication with the body by meansof the wall 12. This wall 12 terminates short of the bottoni of the body10 thereby producing an outlet opening 13 between the tubular member 11and the body 10 as clearly shown in the drawing. This tubular member 11extends vertically of the body 10 to a point near the top of the body orcylinder 10 and is then turned at right angles therefrom for the purposeolf producing an outlet elbow or neck portion 111-.

The body 10 is also provided with an integral collar 15 near the lowerend thereof upon one side thereof diainetrieally opposite the tubularmember 11 as clearly shown in the drawing, constituting an inlet.

r"he cover 19 is threaded or otherwise secured in the upper end of thebody 10 and this cover 19 is provided with an over- 23, 1925. sei-iaiNo. 58,198.

hanging flange 20, the flange 2O projecting beyond the sides ol the body1() to facilitate the reinoval of the cove! from the body 10 when it isso desired. A suitable polygonal head 21 is formed upon the top or thecover 19 to facilitate the rotation thereof within the upper end of thebody 10 whereby the cover may be threaded into or out of engagernentwith the body 10.

The wall 12 which is Jornied between the body 10 and the tubular member11 is provided with an internally threaded aperture or port 22. Asuitable plug 23 may be threaded or otherwise secured vwithin thethreaded aperture or port 22, and it is desired to point out that thisthreaded aperture or port 22 and plug carried thereby are locateddirectly below the water level of the trap or in other words, theaperture 22 is formed in the wall 12 at a point below the lower edge ofthe discharge or outlet opening formed in the neck 14. Conse-l quently,should the plug 23 become loosened or detached from the port 22 byaccident or other inadvertence, the water seal will prevent the escapeof gases through the open end of the body 10 should the cover 19 beremoved therefrom.

lt should be understood that the purpose of the plug 23 is to permit thewaste pipe leading from the trap to be cleaned out in case of stoppageby the insertion of a wire or other suitable tool through the port 22and through the neck 1li.

lt is desired to reiterate the "fact that it is important that the inletand outlet openings formed in the body 10 be located near the bottoni ofthe body so as to at all times insure the complete water seal within thebody 0i the trap and in this way prevent the escape of sewer gases intoa room should the cover 19 be temporarily removed or accidentallydisplaced from the body 10.

As is clearly shown in the drawing, it will be clearly seen that anadditional cleanout port 2a is formed in the side walls 25 of the body10, this port 24 being internally threaded and being adapted to receivea tap plug 26, which is adapted to be threaded into the port 24: andconstitute a closure therefor under normal conditions. This pluri' 26 isadaptedv to have its outer end ext-end flush with the outer end ol theport 24; when the plug is in position. This port 211 is in alignnientwith the aperture 22, and it will be seen that a tool may be insertedthrough the port 24 and engage the plug 23 for the purpose ofunthreading the saine and removing this plug from the port 22. lt Shouldloe further understood that Should the trap becoine clogged, a Yvire orother tool may be inserted through the ports @il and 22 so that accessmight he had to the tubular menil er ll or outlete of the trai. ltshould be lunderstood that the plug 23 inay oe formed ofi brass or other`suitable material Without departing lroin the spirit of the invention,Whereas the plug 25 may lie formed or cast iron.

Having described the invention, what is claimed is:

l. A trap otthe class `described comprising a body Aprovided with aninlet opening and an outlet opening, a vntically entending Wallinterposed between the inlet and outlet opening', the outlet openingbeing placed above the `inlet opening, said Wall heing provided with aclean-out port, a plug for normally closing said clean-out port,

and the outer casing of said trap being provided with an auxiliaryclean-out port in alignment With said clean-out port 'formed in saidWall.

2.19m a new article of manufacture a Waste pipe trap comprising a bodyhaving ,a vertically extending discharge outlet pipe,

the discharge end of which is above the inlet of the aforesaid trap, avertically extending Wall interposed between said outlet and inlet ofthe trap, said Wall provided with an internally threaded aperture, a tapplug normally closing said aperture, and adapted to he removed for tl epurpose of facilitating the cleaning of the outlet opening, and saidbody of said trap provided with an internally threaded port inalignn'ien; with Said port formed in said Wall Yfor facilitating theentrance oit a tool roin the outside of said trap, and a closure plugadapted to norinally close the port 'formed in the Wall ol Said trap.

In testimony whereof allix my, si gnature.
